The density of water is approximately 1 gram per milliliter. Since there are about 236.6 milliliters in a cup, 1 cup of water has a density of about 236.6 grams.
Density is weight by unit of volume, its only dependent on the liquid, not how much of it there is. If you fill the cup from the lake both the water in the cup and the water in the lake will have the same density. But if the water in the cup is from the ocean, and the lake is a freshwater lake, then the water in the cup will have a higher density.
The density of water remains constant regardless of the volume or shape of the container it is in. This is because the mass of water and its volume stay the same, resulting in the same density for both a pool and a cup of water.
A cup of water and a cup of ice would have the same volume and mass because they fill the cup to the same level. However, the cup of ice would have a lower density than the cup of water because ice is less dense than liquid water due to its expanded crystal structure.
In a hot cup, water molecules have more energy, so they move faster and further apart, leading to expansion and lower density. In a cold cup, water molecules move slower and closer together, resulting in contraction and higher density. This difference in movement affects the overall behavior and properties of the water in each cup.
1 8 fluid ounce cup = 236.588237 ml. The density of water is nearly 1 gram/ml. So 1 cup of water has a mass of 236.588237 grams. Note that the mass unit of ounce (16 ounces in a pound) is not the same as the fluid ounce (volume unit).
Sourcream is about same density as water. So 1 cup is about 230 gm.
If you want to determine if the density is greater than water, the easiest method is to place it in a bath of water. If it floats then its density is less than water. If it sinks it is less dense than water. Very few minerals are less dense than water. The other method is to weight the piece and then determine its volume. Dividing the weight by volume with give the density. The density of water is 1 gram per cubic centimeter. Volume of irregularly shaped items can be determined by filling a cup with water to the very brim. Carefully insert the sample into the cup and collect the displaced water in a pan. Weigh the pan and covert the weight of the water to a volume using the density of water. This gives the volume of the sample since each unit of water has replaced by an identical volume of water in the cup.
The object will either sink, float, or remain suspended in the water depending on its density compared to the density of water. If the object is denser than water, it will sink. If it is less dense, it will float. If the object has a similar density to water, it will remain suspended in the water.
You use an overflow cup. You fill it to the top, let the water drip till its done, the insert the object and collect the water that is falling and measure it and you will get your density.
